Abstract:

Objective     To explore the effectiveness of the intervertebral disc ozone therapy for discogenic low back pain. Methods     From May 2005 to July 2009, 72 patients with discogenic low back pain were treated with CT-guided intervertebral disc ozone injection, of which the concentration and dosage were 30-40 ug/ml and 5-10mL, respectively. 66 cases (91.67%) showed positive pain reproduction. Results     All cases were followed up for an average period of 20 months (range from 7 to 54 months). All patients recovered well and returned to their normal lives. Compared with pre-operative period, the average decrease of VAS scoring   and ODI scoring were 50.36 ± 2.32（P＜0.01）and 42.23±5.38(P＜0.01）, respectively. Success rate was  90.28%（65/72）and the effective rate was 100%. There were no infection, nerve root injury, or ozone embolism. Conclusion     Treatment of discogenic low back pain with CT-guided ozone injection is a safe and effective apporach. CT manifestation of ozone injection is similar to Discography.
